Purpose: Human conjunctival cytology has been extensively studied. Lack of data about the characteristics of conjunctival smears in patients treated for retinoblastoma who underwent enucleation and radiotherapy motivated this study. Methods: A previously studied group of 114 orbits of 58 patients was examined. The authors present the results of conjunctival cytology in 4 different situations, with and without enucleation, with and without radiotherapy. Results: In the leukocytic infiltrate in orbits with ocular bulbi predominated the lymphocyte, while in the others predominated the polymorphonuclear neutrophil. In general, the majority of epithelial cell alterations seen in the conjunctival smears of irradiated orbits were: cell with large nuclei, prominent nucleoli, and cytoplasmatic hyalinization. Conclusion: The cytological findings of the conjunctival smears do not indicate a characteristic and distinct pattern for each group.
